Buick LaCrosse Owner Manual - 2011
Driving and Operating 9-35
Notice: Driving with the parking
brake on can overheat the brake
system and cause premature
wear or damage to brake system
parts. Make sure that the parking
brake is fully released and the
brake warning light is off before
driving.
Automatic EPB Release
The EPB will automatically release if
the vehicle is running, placed into
gear and an attempt is made to
drive away. Avoid rapid acceleration
when the EPB is applied, to
preserve park brake lining life.
For maximum EPB force when
towing a trailer or parking on a hill,
pull the EPB switch twice. If you are
towing a trailer and parking on a hill,
see Driving Characteristics and
Towing Tips
on page 9‑56
for more
information.
Brake Assist
This vehicle has a brake assist
feature designed to assist the driver
in stopping or decreasing vehicle
speed in emergency driving
conditions. This feature uses the
stability system hydraulic brake
control module to supplement the
power brake system under
conditions where the driver has
quickly and forcefully applied the
brake pedal in an attempt to quickly
stop or slow down the vehicle. The
stability system hydraulic brake
control module increases brake
pressure at each corner of the
vehicle until the ABS activates.
Minor brake pedal pulsation or
pedal movement during this time is
normal and the driver should
continue to apply the brake pedal
as the driving situation dictates.
The brake assist feature will
automatically disengage when the
brake pedal is released or brake
pedal pressure is quickly
decreased.
Ride Control Systems
Traction Control
System (TCS)
The vehicle has a traction control
system that limits wheel spin. This is
especially useful in slippery road
conditions. On a front-wheel-drive
vehicle, the system operates if it
senses that one or both of the front
wheels are spinning or beginning to
lose traction. On an All-Wheel-Drive
(AWD) vehicle, the system will
operate if it senses that any of the
wheels are spinning or beginning to
lose traction. When this happens,
the system brakes the spinning
wheel(s) and/or reduces engine
power to limit wheel spin.
The system may be heard or felt
while it is working, but this is
normal.
